Your best choice is to consult one of the two links I posted and to acquire your own access to either ALLDATA or Mitchell One repair manuals. In there you will find everything you want to know.
This forum is not really intended to direct folks on how to carry out step by step repair procedures. If you have a pointed question about a specific problem or repair process, we can help.
What I think you are looking to know is basically that the axle does not have to come out of the transmission, but of course must be separated from the hub. You will need some press tools on site to do this procedure.
Can you do this in your driveway? Sure, provided you have the right tools to get it done. Good luck!
